There are a pair of tie plate adaptedfor application to a, ti d rail clips 9 and a description of one of themwill having flanged outer edges and shouldered side ce be au th y are dpl h r il lip edges adapted to abut on the opposite edges of 9 is curvedin consonance with the rail base and the rail base, a pair of clipanchors adapted reweb and it abuts on the flange 2 and it is pspectively to abut at one end on the tie plate vided with a T slot 10adapted to receive the T outer flanges and each having at the other endan head 5 and to be held down thereby. The tie upstanding T head adaptedto bear on the adcl ps extend over the rail base and up the web jacentedge of the rail flange and each having a of the rail to the neutralaxis. ll indicates aknee loop extension adapted to pass under andfriction and compression agent such as Masonbear on the rail base and tolie alongside the tie ite (compressed wood) or rubber, and it is inandextend to the opposite edge of the rail base, a terposed between therail, shoulder, and tie plate, pair of rail clips curved in consonancewith the and between the rail clip and rail web and base. rail base andweb and each adapted to abut on 12 indicates screw spikes for attachingthe described fastening, which is locked to the rail, in place on thetie.

From the foregoing description it is evident that the entire rail baseabove the tie plate and the web of the rail up to the neutral axis ofthe same is used as a bearing agent in fastening the rail to the tie.This increases the bearing area and stress distribution area from theusual four square inches to fifty-six square'inches or thereabouts andthe above area. is coupled to the opposite side of the rail base througha common anchorage, using the rail itself for hold down anchorage. Inassembling the parts the tie .plate I is first placed on the tie b. andthe rail a is then placed on the tie plate with the edges of its base incontact with the flanges 3. The clip anchors 4 are then applied withtheir T heads 5 in contact with the edge of the rail base and to oneside of the flange 3 and the outer edges of the clip anchor are incontact with the tie plate flanges 2. The knee loop extensions passalong the tie and under the rail and the knees I abut on the bottom ofthe rail base, the hook 8 engages the head of the rail base opposite theedge where the slip anchor is arranged. The hook 8 may be hammered orotherwise forced into contact with the rail base. The rail clips 9 arethen applied with the T heads 5 through the T slots l and they aredriven inward until their outer edges lie in engagement with the flanges2 of the tie plate. The rail and rail fastening are thus completelyinterlocked so that they act as a unit rather than as independent parts.The function of the screw or other spikes I2 is merely to connect therail fastening and the tie and during the assemblage of the parts of thefastening the openings l3 for the screw or other spike [2 are broughtinto alignment. The holding power and frictional resistance of thefastening opposes creeping of the rail in either direction. Furthermorethe bracing action of the described fastening checks sidewise stresses.The Masonite or other material which is compressed between the shouldersof the tie plate and between the base of the rail and top of the tieplate prevents cutting or wearing of the tie plate by direct contact ofmetal or metals and furthermore that material has a sound deadeningeffect and eliminates noise to a great extent. It may be remarked thatthere are no bolts or the like for securing the rail fastening to therail and in the usual type of rail fastenings the stresses from the railto the fastener is distributed entirely through a bolt or the like whichis constantly being worked or stressed. The described parts of thefastening can be manufactured at little expense and are easily andquickly assembled.

Since the extensions 6 lie on opposite faces of a tie b, they serve tosquare the tie and the rail and rail fastening. When the extensions 6,are in the form of loops they are springy which is an advantage in somecases. The purpose of bevelling or undercutting the ends of the clipanchors 4 and rail clips 9 is to facilitate their assembly in theflanges 2 by driving them after they have been properly mounted inrespect to the rail. The outer walls of the head of the T-slot III, arealso bevelled or undercut to facilitate the entrance of the T-head 5when the rail clips are driven to place.

The embodiment of the invention described is particularly adapted tohigh speed railroad interurban open track speedway and elevated trackconstruction but for other uses itis not always necessary or desirableto use the complete conlips 9' for engagement with the upper surface ofthe rail base.

It will be obvious to those skilled in the art to which the inventionrelatesthat modifications may be made in details of construction andarrangement and in matters of mere form without departing from thespirit of the invention which is not limited to such matters, orotherwise than the prior art and the appended claims may require.

Means for fastening railway rails to ties comprising the combinationof a tie plate adapted for application to the top of a tie and havingside flanges and intermediate shoulders, a pair of clip anchorssuperposed on the tie plate and each adapted to bear on one of saidflanges and having an up-standing T head wholly located above the tieplate and aligned with one of said shoulders and having a knee loopadapted to'extend at the side of the tie plate into alignment with the Thead ofthe other clip anchor and there engage the bottom side and top ofthe rail base as well as engage the opposite under face of the railbase, rail clips having T slots adapted to receive said T heads and toabut on the flanges of the tie plate and on the base and web of the railand means securing said plate, anchors and clips to the tie.

3. Means for fastening railway rails to ties comprising the combination'of a tie plate underlying the rail and overlying the top surface of thetie and having upstanding side flanges and intermediate shoulders saidshoulders being adapted to engage the edges of the base of th rail, clipanchors superposed on the tie plate nd having up-standing T heads andprovided with extensions adapted to engage the under face of the base ofthe rail and also one edge of the far side thereof, rail clips havingslots for the T heads and adapted to engage the top of the base and asubstantial portion of the web of the rail, and means for securing theclip. anchor and rail clip to the tie plate and tie.

4. The combination substantially as described in claim 3 in which saidsecuring means comprises spikes which penetrate the rail clips, clipanchors, and tie plate and enter the ties to hold down the fasteningelements and rail to the tie.

5. Means for fastening railway rails to ties consisting of a tie-plateadapted for insertion between the upper surface of the tie and thebottom surface of the rail and shouldered intermediate its side edges toengage both edges of the rail base and having upstanding flanges at saidside edges, a pair of clip anchors having T-heads overlying the tieplate and other means underlying the rail base at each edge thereof, apair of rail clips engaging said upstanding flanges and also the upperface of the rail base and parts of the web and having T-slots engagingthe T- heads, whereby said anchors and clips are adapted to be clampedtogether and to the top and bottom parts of the rail base and to therail web, and. means for securing the clip anchor and rail clip to thetie plate and tie.

6. Means for fastening railway rails to ties consisting of a pair ofclip anchors adapted to be disposed at the respective sides of a railand each having an extension arranged along the side of the tie andadapted to under span the rail and to engage the under face of the railbase at both sides thereof and to engage the far edge of the rail base,a pair of rail clips adapted to be superposed on the clip anchors andshaped to engage the top face of the rail base and a portion of the web,means interposed between the rail clips and clip anchors for clampingthem together in pairs, a tie plate upwardly flanged to engage the railbase and the ends of the clips and adapted to be superposed between thetop surface of the tie and the rails, anchors and clips, and meanssecuring said anchors and clips to the tie.

'7. In means for fastening rail way rails to ties, a tie plate, clipanchors and rail clips arranged on top of said plate on the same singletie, T-heads on said anchors and T-slots in said clips located whollyabove the tie plate and interconnecting.
